# std::basic_ospanstream<CharT,Traits>::operator=

From cppreference.com
< cpp‎ | io‎ | basic ospanstream

basic_ospanstream& operator=( basic_ospanstream&& other ); | (1) | (since C++23)
basic_ospanstream& operator=( const basic_ospanstream& ) = delete; | (2) | (since C++23)

1) Move assigns the other to *this, effectively move-assigning both the std::basic_ostream base class subobject and the wrapped std::basic_spanbuf.
2) Copy assignment operator is deleted. `basic_ospanstream` is not copy assignable.

Note that move assignment operator of the base class swaps all stream state variables (except for `rdbuf()`) between *this and other.

It is implementation-defined whether the std::basic_spanbuf wrapped in other still holds an underlying buffer after the move assignment.

### Parameters

other | - | another stream to move from

### Return value

*this

### Exceptions

May throw implementation-defined exceptions.
